Former Arsenal striker John Hartson believes Unai Emery will regret allowing Aaron Ramsey to leave the club, with the Welshman set to depart in the summer when his contract at the Emirates expires.
Ramsey has been a Gunners player for a decade, having joined the club from Cardiff City in 2008. Nevertheless, his long affiliation with the north London club seems to be coming to an end as the Welsh midfielder's contract teeters towards its expiration date.
Despite Arsenal's willingness to let Ramsey leave, Hartson believes it is a mistake as the Welsh midfielder still has a lot to offer.
